SINGLE-TRIGGER MECHANISM FOR GUNS.

Specification of Letters Patent.

Patented Feb. 27, 1906.

Application filed August 27,1903. Serial No. 170,938.

To all 7.1;71/0711/ it may concern:

Be it known that I, GARRET B. OSTER- HOUT, a citizen of the United States, residing at No. 913 Greene avenue, in the borough of Brooklyn, in the city of New York, county of Kings, and State of New York, have in vented a certain new and useful Improvement in Single-Trigger Mechanism for Guns, of which the following is a full, clear, and exact description, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

Figure 1 is a vertical longitudinal section view. Fig. 2 is a plan view, the upper tang being broken away. Fig. 3 is a side elevation view with the plate which trips the right sear removed and shown in dotted outlines. Fig. 4 is a side elevation viewed from the right side. Fig. 5 is a side elevation viewed from the left side. Fig. 6 is a side elevation view showing an attachment whereby the mechanism may be shifted and the left sear tripped first. Fig. 7 is a bottom plan view of the shifting mechanism.

This invention relates to new and useful improvements in single-trigger mechanism for guns having a plurality of barrels, the ob ject being to enable the operator to successively release or trip the firing mechanisms by the manipulation of a single mechanism in the form of a trigger and to prevent the discharge of the second barrel by the concussion caused by the discharge of the first barrel.

With this object in view my invention consists in the novel construction, arrangement, and combination of the several parts, all as will hereinafter be described, and afterward pointed out in the claims.

In the drawings, 1 indicates the barrels, 2 the frame, 3 the fore-end, 4 the pivot by which the barrels and fore-end are pivoted to the frame, 5 the top lever, by which the barrels are locked to the frame when the gun is closed, 6 the hammer, 7 the mainspring, 8 the left sear, 9 the right scar, and 10 the springs which operate the scars, 11 a post forming a part of or rigidly attached to the frame, all of which parts are practically the usual and well-known construction of the firearm commonly called double-barreled hammerless shotgun.

The general construction and operation of a double-barreled hammerless shotgun are well understood and a detailed description is hardly necessary, but for purposes of explanation may be briefly described as follows: The gun shown is of the breakdown type, and upon the release of the barrel-locking mechanism by the manipulation of the top lever 5 the barrels swing on the pivot 4, which in addition to actuating the ejecting mechanism also operates the cooking mechanism and brings the hammers to full-cock.

12 is a post rigidly attached to the frame, to which is pivoted an angle-plate 13 by means of the screw 14.

15 is a tripping member pivoted; by means of the screw 16, to the angle-plate 13. This tripping member is provided with a slot 17, which registers with'the left sear 8. It is also provided with a pin or shoulder 18, projecting from its inner face. I Another tripping member 19 is pivoted to the frame of the gun by the pin 24 and is fitted into the slot in the frame in which the trigger for the right barrel is usually fitted, and this tripping member 19 is provided with a slot 20, with which the sear 9 of the right lock of the gun registers, also with a slot 21, which registers with a pin or projection 22 on the plate 13.

23 is the trigger, which is pivoted to the frame in the usual manner by the pin 24 and is provided with two shoulders 25 and 26.

When the hammers are at full cock, the end of the right sear 9 is somewhat elevated, and the tripping member 19 is raised thereby, and the plate 13 and the tripping member 15, pivoted to the same, are forced forward in such a position that the shoulder 25 of the trigger registers with the pin or shoulder 27 on the inner face of the plate 13, so that when the trigger is pulled the shoulder 25 is elevated and the plate 13 pushed upward, carrying with it the tripping member 19 and tripping the sear 9 of the right barrel. WVhen the sear is tripped and the hammer falls, the tripping member 19 is forced downward and backward by the sear 9, and the plate 13 and the tripping member 15 pivoted thereto are forced backward, so that the pin or projection 18 on the tripping member 15 registers with the shoulder 26 on the trigger, and when the trigger isagain pulled the shoulder 26 presses against the pin or shoulder 18, and the tripping member 15 is elevated and the sear 8 of the left lock tripped and the left bar- I i rel discharged. 5

On the post 11 is a shoulder or pin 28, beneath which the tripping member 15 is forced when both locks of the gun are cocked. This IIO prevents the tripping member from being elevated and locks the sear of the left lock, so that the left barrel cannot be discharged until the right barrel has been fired and the pressure on the trigger has been released and the mechanism forced backward by the falling of the sear 9, when the left barrel has been discharged.

29 is a spring for taking up the lost motion of the trigger.

In operation the recoil resulting from the discharge of the right barrel releases the pressure of the finger upon the trigger, so that the angle-plate 13 and the tripping member 15 are free to move backward under pressure of the sear 9, and the parts are then in position for discharging the left barrel.

It is sometimes desirable to fire the left barrel first. I have shown in Figs. 6 and 7 a projecting part 30, forming a part of the plate 13, which extends beyond the frame of the gun and has a spring portion 31 and angular grippiece 32 and a catch 33, adapted to engage the recess 34 in the frame. I/Vhen it is desired to fire the left barrel first, the finger is placed against the angular grip-piece 32 and the parts are drawn backward until the catch 33 engages with the recess 34, which retains the tripping member 15 in position to engage with the trigger and trip the left sear.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is

1. In a gun a safety device which consists of a shoulder or projection on theframe of the gun and a longitudinally-movable tripping member engaging with the sear, which is adapted to be interposed between said shoulder or projection and the end of the sear so that the sear cannot be released and means for moving said tripping member out of engagement with said shoulder or projection so that the mechanism can be fired, substantially as and for the purposes described.

2.
